To all whom it may concern.-

Be it known thatl, EDWARD P. lVAGGONER, of Syracuse, county of Onondaga, in the State of New York, a citizen of the United States, have invented certain new and useful Inn proveineuts in Piping Systems, of which the following is aspecificaticn, reference being had to the accompanying drawing.

My invention relates to systems for piping lmildings for tire purposes adapted to use an t niatic sprinklers and other appliances under pressure p The objectof my invention is to furnish a simple compact system adapted to use water either from a water-main or from a tank on the roof, and also the filling of the pipes with anion-freezing chemical or otherpreparation" two stop-valves t and 5, being nearer the tank and i nearer the first door of the building, and 6 is a check-valve adjacent to the stop-valve t. 7 another check-valve adjacent to the stop-valve 5, To the stand-pipe2 the s J1'inkler-pipes S and 3 are connected in v any ordinary manner, and each is provided with a cut-off valve 10. v

11 are the automatic s n-inhler-heznls used upon the pipings.

i h is a mixing-tank, in which l mix up the chloride of sodiuin or other chemical solutions from the pipe 12, opening out of the tank above the bottom, to allow for settling of the chemicals, carrying the saturated solution into the storage-tank ll, whence the pipe conducts it to the forcopuinp I, and from this pipe 13 conducts it to the stand-pipe i Inthis pipe 131 place a chcclcvalve l-l and stopvalve 15, and to this pipe, between the stop- "alve and Island-pipe 2, i connect the drippipe 16, provided with a stopvalvc 17. This pipe is the drai nage-pipe, through which I can draw off all the water in the piping s or:

any purpose by shutting the stop-valves l and 5. -When I have so drawn off the Water from the piping, lclose the valve 17' and open the valve 15. To fill the system under pressure, the valves 4 and 5 being closed, I then operate the pump and force the prepared liquid through the pipe 13 into-the pipe 2,and thence intojche pipes 8 9, filling them with the solution and forcing it into" them until the pressure upon the gage 18, connected to the stand pipe 2, indicates a pressure at least equal to twenty pounds per square-inch above the pressure from the tank E or pipe 1 exerted upon the stand-pipe 2. The construction of this gage upon the valves 4 and 5 in the main supply-pipe will not be specifically here given, beeause l'inteud'to make it the subject-mats, t'er of a subsequent application, so thatI will simply say that the face is provided with an adjustable electrical contact-point, to which one of wires, as 19 or 20 in the circuitshown, is connected, the other wire being also connected to the arbor of the needle in the gage, so that when the needle is in contact with. the contact-point thecircuit is completefrom. the battery 2lone way on the gage and the other way on the bell 22and from the bell to the gage, so that whenever from any cause the water-pressure in the stand-pipe 2 is rcduced by leakage, by the opening of the sprinkler-head, &c., the removal of themeedle to the contactppoint closes the circuitand sounds an alarm upon the bell. 7

At 23 Ishow a switch by which I cut out. the bell whenever desired-as, for instance,

when I ainfilling the pipes with the solution,

and also for testing the belland battery.

It is operated as follows: Having prepared the nonireezing liquid in the tank or tanks, and the pipes through the building being empty and the valves 4 and 5 being closedaud 15 opened, Loperate the pump 1, drawing the liquid from the tank and forcing it through the pipelB into the main pipe 2, and thence into the (:eiling-pipesS 9, filling them and com tinuing the pumping until the pressure on the gage 18 indicates a pressure of, say, twenty pounds per square inch greater thansthe pressure in the water-main 1. Then when the valve 5 is open the water'from the main cannot pass upward into the piping against the increased pressure, nor can it open the check valve 7, and in like manner when the valve 4.

is open the, check-valve 6 will prevent the I liquid from entering the tank E.. After having obtained this pressure I close the valve 15. Then when the pressure, either from leakage or from the opening of an automatic sprinkler-head 11, is reduced the operation of the needle of the gage connected to the battery and bell will 'sound an alarm upon the the tank E or from the water-main will replace the non-freezingliquid in the pipes and operate to extinguish the fire, and in case the rain; E becomes emptyall the Waterwill new fro'm the Water-main, the check-valve. 6 preventihg the flowing of Water into the tank E. It will be observed that thus the stand-pipe, exterior to either or both check-valves, is nor- ".nifally filled with the non-freezing liquids,

which are separated from the fresh water by tile check valve or valves, and that whenever a sprinkler is opened the check .valve or valves wi 1 open to admit fresh Water into the standpipe to replace the liquid-discharged through the sprinkler; and it will be further seen that by keeping the piping full of this liquid there is no danger of the'pipes freezing up in the coldest weather, even in a building in which there is no heating apparatus.

What I claim as my invention is i 1. A piping system for fire purposes, com prising a main -stand-pipe, branch pipes earrying automatic sprinklers, a tank upon the roof connected to the main stand-pipe,a storage-reservoir, and a pump connected to the reservoir and to the main stand-pipe, substantially' as described.

2. A piping system for fire purposes, consisting of a main stand-pipe connected to a avater-main, branch pipes carrying automatic sprinklers connected to said main, a stopvalve 5 in said main, a reservoir,-and a pumpconne'cted to the reservoir and to the standpipe above the stop-valve, substantially as described. 7

' 3. A piping system for tire purposes, comprising a stand pipe connected at the lower end 10 the water-main, at the upper end to a tank on the roof, and provided with stop-valves 4 and 5 and check-valves 6 and 7, branch pipes carrying automatic sprinklers connected to the main pipe,"a reservoir connected to a pump, a pump, and a pipe provided with a stop and check valve leading to the standpipe, substantially as described.

4. A piping system for fire purposes, cum

sisting of a main stand-pipe connected to a water-supply, branch pipes carrying auto-- matic sprinklers connected thereto to the stand-pipe, a stop-valve 5 in the stand-pipe, a reservoir, and a pump connected to the reservoir and to the stand-pipe above the stopvalve, in combination with a pressnre gage connected to the stand-pipe above the stopvalve, a battery, an alarm-bell, a circuitc'oir nesting the gage and bell to the battery, and

a switch to disconnect the bell from the circuit.

In witness whereof I have hereunto set iny In presence of v H; P. DENISON, F. T. DENIsoN.
